Reviewers need to make sure their report is useful to the Editor and the authors. With that in mind, which of the following statements is correct?

The report must always include comments to both the Editor and the authors
The report should only focus on the weaknesses of the manuscript
If the reviewer feels that the article doesn’t fit the aims and scope of the journal, they only need to suggest rejection and don’t need to include any further detail
The comments to the Editor are not shared with authors, so detailed concerns that can help improve the article should be included in the comments to the authors
